I agree with everyone above. You'll really like the 1862, very strong machine. I actually find my turning radius on my 1864 (almost the same tractor) to be very tight, and the power steering makes it effortless.
My only comment is that with 900 hours you need to have an idea of how well maintenance was performed on the tractor. If oil wasn't changed, engine wasn't kept clean of gunk, it may need rebuilding sooner. If the deck looks beaten up, spindles not greased, you may be looking at new spindles and some welding.
So, if the 1862 looks reasonably clean and well cared for I'd go for it. If it sat outside and wasn't maintained, keep looking but I really like the value of that series of tractor.
